| USGA Summary Points: | Clipping weights were reduced similarly (~≥60%), regardless of rate with suppression duration being rate dependent (Table 2). This lasted for ~10 days at 1 oz/ac, 24 days for 2 oz/ac, and over 28 days for 4 oz/ac. Primo Maxx at 16 oz/ac provided similar reduction for ~24 days. Repeat applications 28 days after the initial extended clipping growth reduction through 21 days after the sequential one (Table 2). Turf color response to PGR applications was measured in two ways: (1) visual phytotoxicity (%); and (2) electronically via Normalized Difference Vegetation Index (NDVI) (0 to 1) ratings. Visual phytotoxicity for any treatment never exceeded the maximum level deemed acceptable (30%) (Table 3). Greatest phytotoxicity (~10%) followed the highest rate of Plateau examined (4 oz/ac) and lasted for 24 days. Approximately 8% phytotoxicity followed Primo Maxx at 16 oz/ac and lasted for ~10 days. Repeat applications caused turf phytotoxicity for the 4 oz/ac Plateau from 14 days (10%), to ~8% at day 21 and ~4% at day 28 following the sequential application. No differences in NDVI ratings occurred throughout the study for any product at any rate (Table 4). |
